FURNACE-CLEANER SPECIFICATION formingpart of Letters Patent No. 613,590, dated November 1, 1893.

Application filed Deenibef 21, 1897. Serial No. 662,870. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES MELROSE MOGAMEY, of Denver, in the county of Arapahoe and State of Colorado, have invented a new and Improved Furnace-Cleaner, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved attachment for fire-boxes of steam-boilers, assayv and other furnaces, oven-grates, 8m, and arranged to permit of quickly and conveniently removing ashes, clinkers, and other solid matter from a grate directly into an ash-pit.

The invention consists of novel features and parts and combinations of the same, as

will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a perspective front elevation of the improvement. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1, and Fig. 3 is a sectional side elevation of the same on the line 3 3 of Fig. 1.

The setting for the furnace or other device on which the improvement is applied is provided with the usual inlet or fuel-charging doors A, leading to the grate Bin the fire box, the said grate being arranged to discharge the ashes directly into an ash-pit C in the usual manner.

In the dead-plate or bottom E of the inlet A and preferably close to the grate B is arranged an opening E, normally closed by a cover F, fitted to slide on the said dead-plate, the said cover being preferably provided at its forward end with sidewise-extending lugs F, having a limited movement between stoppins G, attached to or formed on the sides of the inlet A.

On the top of the cover F is preferably arranged a rib or boss F adapted to be taken hold of by a suitable tool to push the cover F outward to uncover the opening E or to push the said cover inward to close the said opening. When the cover F is in an outermost position, the opening E is uncovered, and clinkers or other hard substances can be readily raked out by suitable tools into the inlet or filling door to drop through the open= ing E directly into the ash-pit 0 below. When the clinkers or the like have been removed,- the cover F is again pushed inward to its normal position to close the opening E.

The under side of the dead-plate E is preferably formed with strengthening-ribs E around the walls of the opening E to give the desired strength to the dead-plate.

In order to prevent an accumulation of ashes or small particles of fuel between the lugs F and the stop-pins G, I provide the dead-plate E, adjacent to the stop-pins, with apertures H, through which the ashes or small particles of fuel can readily pass to the ashpit below, so as not to interfere with the free movement of the cover F.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A furnace having a rigid and immovable dead-plate located forward of the grate-bars and provided directly adjacent to the gratebars with an opening through which clinkers may be discharged into the ash-pit, the deadplate being also provided on its top face at points forward of the opening with stop-pins located two at each side of the dead-plate and separated from each other, and a cover mounted to slide forward and back on the top face of the dead-plate and provided at each side near its front with a sidewise-extending lug, the lugs being respectively movable be-- tween the pairs of stop-pins whereby to limit the movement of the cover, and the cover being also provided on its top face with a rib running transversely to the dead-plate.

2. A furnace having an immovable and rigid dead-plate located forward of the gratebars and provided with an opening through which clinkers may be dropped into the ashpit, and a cover commanding the opening and mounted to slide forward and back on the dead-plate and in a plane parallel with the plane thereof, the cover being supported by continual engagement with the top of the dead-plate.

CHARLES MELROSE MCOAMEY.
